Abstract
However, climate change, resulting from increasing atmospheric concentrations of greenhouse gases, could have significant effects on water resources. Climate change is consistently associated with changes in a number of components of hydrological cycle and systems such as: changing precipitation patterns, intensity and extremes; widespread melting of snow and ice; increasing atmospheric water vapor; and change in soil moisture and runoff [1]. For example, the increasing frequency or magnitude of extreme rainfall events occurred in the winter or spring when the ground was frozen or soil moisture levels were high, producing more rapid runoff and greater flooding.
Highlights
Drought is the most complex of all natural hazards
The results showed that the North American Regional Reanalysis (NARR) data could provide valuable, independent analysis of the water and energy budgets for various land uses in Florida
The new regional land use drought indices were developed from normalized Bowen ratio and the results showed that they could reflect the level of severity in drought events resulting from land use effects, and La Niña driven drought impacts
Summary
Drought is the most complex of all natural hazards. The lack of progress in drought preparedness planning and the development of national drought policies are reflections of this complexity.
